while ishandle(1)
% Capture the image from the camera on hardware.
img = snapshot(camObj);
% Detect objects in the frame
[bboxes, scores, labels] = yolov3Obj.detect(detector, img);
% Annotate the image with bounding boxes and labels
img = insertObjectAnnotation(img, 'rectangle', bboxes, cellstr(labels));
% Display the annotated image

I am trying to run this code in order to generate an .exe of this code to my Jetson Nano Developer Kit
>> inputArgs = {coder.Constant(camName),coder.Constant(camResolution)};
codegen('-config ',cfg,'-args',inputArgs,'YoloOnJetson','-report');
The 'yolov3ObjectDetector' class does not support code generation.
Error in ==> YoloOnJetson Line: 20 Column: 12
Code generation failed: View Error Report
Error using codegen
I usually get this error, I do have the darknet53-coco.mat file in my file directory, I did generate it somehow playing around.
It's werid because yolov3ObjectDetector shall be compatible with code generation, what can I do?

if isempty(yolov3Obj)
yolov3Obj = coder.loadDeepLearningNetwork('darknet53-coco.mat');
end
That step looks good: you are loading a pre-trained detector that should be of the right class.
detector = yolov3ObjectDetector('darknet53-coco');
But there you are trying to create a new object of that class. Creating a new object of the class is not supported in deployed code: all you can do in deployed code is load an already-trained detector and use the detect() method of that pre-trained detector.
